The theoretical basis is developed and the idea to practical production and testing of the semiconductor electric generator (thermobattery) of a new type acting metal on the system basis – the semiconductor is offered. It is shown that the thermobattery will work at a basis of use of a volume (space) thermogradient effect. Sufficient level of generirumy power from volume unit of semi-conductor material allows to gain this effect.  When using the semiconductor thermobattery in a complex with solar and wind electric generators it is possible to simplify significantly constructional and technological features of these installations.
